A constant frustration of mine is people who park in handicapped parking spaces (and fire lanes). It's all too often that I see someone parked in the space and doesn't have a placard, or they're parked in the hash marks which are designed to give space for a ramp or lift to get a wheel chair in and out of a van or car. No, those spaces are not for motorcycles.
As as solution to this, I've thought that incorporating a curb around this area would prevent cars from parking in these spaces. The yellow line in the picture below represents where a curb should go. This would require that a ramp or curb cut at the other end of the space be provided (down where the signs are placed). The major drawback to this would potentially be that it makes it more attractive to motorcycle owners as a protected space, and could make it difficult to clear of snow in the winter as it couldn't be plowed.
Ultimately, as our population ages, and more baby boomers are losing their mobility, it seems like there's greater awareness of accessibility and universal design. Perhaps this will filter over to better urban design as well.
